Abstract

AbstractOne of the promising areas for intensifying the mass transfer process is the improvement of separation columns using a stabilized foam mode of interaction of gas-liquid flows, including movable nozzle bodies. A new design of the stabilizer with a sizeable free volume and a spherical movable nozzle was developed. The advantage of the proposed design is the transition to a structured foam mode of operation at relatively low gas speeds and a developed phase contact surface. After experimental studies of the hydrodynamic characteristics of the combined contact element, empirical data on hydrodynamic resistance and experimental indicators of spray attribution for a contact stage with combined contact elements were obtained. As a result of research, it was found that when using foam layer stabilizers, the spraying ratio at the contact stage is reduced, which leads to a more stable operation of the device. An empirical equation for determining the value of the spray attribution is given.KeywordsHydrodynamicsStabilizationFoam layerHole plateTurbulizationMovable nozzleSpray removal reducingEnergy efficiency
